12 Claims; (Cl. 1-219 l The present invention" relates to a machine for use in the automatic fabrication of printed circuit boards and more specifically to a device for clinching the wiresof a I United States Patent C) 3,157,77 Patented Feb. 2, 1965 "ice quence; applying pressure or support to a circuit board from beneath the circuit board, between the leadwires of an inserted transistor, bending the leads radially outward,

" and then clinching them flat to the circuit board.

. Other objects of the present invention will be-appajrent' from the following'description taken. in: conjunction zwith the accompanying drawings, wherein:

radial lead'electrical component to the bottom of a board after its insertion. More particularly, the machine pro vides for radially outward positioning of lead wires while the electrical component is held tightly to the board.

Cli'nchin'gdevices are common in the art for such electrical componentsas resistors, diodes, and capacitors, which possess only a pair of lead wires arranged within a single plane. The most common of these clinchingdevices comprise rotary anvils, mounted beneath the printed circuit board, which wipe across the wires protruding therethrough to bend each down in a line approximately a tangent to a circle through the lead roots whose center would be the midpoint between them. Therotary clincher is not feasiblewhere three'or more lead wires are present due to the possibility that after clinching the ends of the wires will overlap andcause a short circuit.

, Other common clinching devices util' e pairs of pivoted or reciprocating benders, with individual elements for bending'each lead wire. Such a device becomes extremely expensive and complicated when three or more lead Wires are present and an equal number of benders are needed; -The-use of multi-lead radial components has become widespread with the advent of transistors and the more recent micro-modules and'other small inte- FIG. 5 (A, B, C, and D) is a series ofdiagrammatic representations, in sequence, of the relationship of the elements of the lead bending and clinching unit during the clinching of the leads of a three lead transistor.

Referring to the'drawing, FIGS. 1-3 in particular, the lead bending and clinching unit, generally designated 10, has a main" body section, generally designated 12 con- 'sisting" of a horizontal base plate 14 and an outwardly extending arm 15 comprised of a pair of parallel vertical side members 16 withfan interconnecting perpendicular web 18 extendings'the length of said side "membersl. The outer ends of the arm 15 terminates in a cylindrical f tube 20 having a vertical .axis. A pair of parallel cars 22 extends. downwardly, one from each of theside memgrated electronic assemblies necessary dueto the trend 7 toward miniaturization;

The holding of the electrical component to the printed circuit board with enough pressure to clinch the leads close enough-to the board to hold the component securely 'alsopresents a problem. Very often, the required pressureon the .ripper face of a component from-above, will buckle the-board'downwardly, causing a separation between the board 's'urfaceand the circuitry thereon and It is a general object of the present inyentidnto proatum.

Looking at FIG. C, the anvils 34;.and 56-are now .driven upward by an application of fluid pressure to the fluid actuator114 which is either manually activated or automatically controlled in relation to the application of pressure to, the actuator 136 in. any known manner.

As the combination of the anvils 34 and 56 raise upward, the spring 82 holds the inner anvil 56 extended so that the beveled face 68 thereof will bend the lead wires 166 radially'outward. After the inner anvil 56 has been completely extended and has partially folded over the leads 166, the outer anvil 34 continues to move upward compressing the spring 82. The flat face 44 of the outer anvil 34 forces the lead wires 166 flat against the bot;

tom face of the circuit board 164 (FIG. 5D). The fluid pressurein both actuators 114 and 136 is now vented releasing the board 164 with its clinched component 1.61.

The forming faces 68 and 44 of the outer and inner air space is left between the body 162 and the board 164 for ventilation.

It willbe obvious to those skilled in the art that various changes may be made without departing from the spirit of the invention and therefore the invention is not limited to what is shown in the drawings and described in the specification but only as indicated in the appended claims.

What is claimed is 1 j l. Anelectrical component handling device for bending and clinching the leads of components to a board, each component having abody section and a series of parallel wire leads extending outwardly from a side thereof,

2. The handling device of claim 1 wherein said bending and clinching means is at least one cylindrical tube having a coaxial passage. extending therethrough and said clamping rod extending throughsaid coaxial passage.

If the anvils were of a polygonal cross section, an added advantage ac-Q cruing would be thatthey could-not rotate and the key and slot could be omitted.
